Colds
A cold or upper respiratory infection is an infection of the nose and throat caused by a virus. Symptoms of a cold may include a runny or stuffy nose, fever, sore throat, cough, red eyes, or swollen lymph nodes in the neck.
The cold viruses are spread from one person to another by hand contact, coughing, and sneezing. Colds are not caused by cold air or drafts. Because there are up to 200 viruses that cause colds, most healthy children get at least six colds a year.
Many children and adults have a runny nose in the wintertime when they breathe cold air. This is called vasomotor rhinitis. The nose usually stops running within 15 minutes after a person comes indoors. It does not need treatment and has nothing to do with cold or an infection.
